Abstract
Official abstract text for this publication.
A photocatalyst, represented by the following general formula (1): X(VO 4 ) 6 (OH) 2 General Formula (1) wherein X represents Z a1 Ti b1 or Z a2 Ti b2 Ag c2 (where Z is Ca or Sr; a1 is 7.0 to 9.5; b1 is 0.5 to 3.0; a2 is 7.0 to 9.5; b2 is 0.4 to 1.5; c2 is 0.1 to 2.0; a1+b1 is 9.0 to 10.0; and a2+b2+c2 is 9.0 to 10.0) in the general formula (1).
First claim
Opening claim text (preview).
What is claimed is: 1. A photocatalyst, represented by the following general formula (1): X(VO 4 ) 6 (OH) 2 General Formula (1) wherein X represents Z a2 Ti b2 Ag c2 (where Z is Sr; a2 is 7.0 to 9.5; b2 is 0.4 to 1.5; c2 is 0.1 to 2.0; and a2+b2+c2 is 9.0 to 10.0) in the general formula (1). 2. A method for producing the photocatalyst according to claim 1 , the method comprising: blending a vanadium-containing compound, a strontium ion-containing compound, a titanium ion-containing compound, and a silver ion-containing compound together. 3. The method according to claim 2 , wherein the vanadium-containing compound is vanadium pentoxide.
